Multitasking. You can now run multiple—meaning “up to three”—applications at the same time.

Input improvements. You can now connect a normal Bluetooth mouse to your HoloLens, and the HoloLens clicker has been fine-tuned to enable resizing and moving of holograms.

Voice improvements. Microsoft has added some new voice commands. For example, when viewing a hologram, you can say “Face me!” to re-orientate it. You can also say “Bigger” or “Smaller” to resize a hologram, and you can move an app by saying “Hey Cortana, move [app name] here.”

Edge improvements. Microsoft Edge now supports many of your requested (and obvious) feature such as multiple instances of the browser, a custom HoloLens New Tab page, Tab Peek, Open in New Windows, and various power and performance improvements.

Photos improvements. The Photos app now supports the pinning of pictures without any borders or chrome. Your walls will never look the same, Microsoft says. It also now streams videos from OneDrive instead of having to download the entire video before playback.

Easier development. Now, you can now browse, upload, and download files through the Windows Device Portal, and you can access the Documents and Pictures folders, and the local storage for any app you side-loaded or deployed through Visual Studio.
